(ci. 21o-99) Thisbotue has the cap 2 over its mouth.v The cap is preferably screw threaded on the bottle neck and has a central opening'S. Between the end of the bottle neck and the cover of the cap is la washer 4 having an opening aligned with the opening 3. This washer is preferably of a resilient material such as rubber or felt,` insuring a tight fit between the bottle mouth and the cap. Extending through fthe openingA 3 in the cap 2 andl the` opening in the washer 4 is the 'plunger 5 having the closure plate 6l on the inside of the bottle. Aroundthe plunger is the spiral spring 'Y having one end contacting with the cap ofthe bottle and the other with the stop plate 8, adjacent the outer end of the plunger. K'

The bottle is supported by the lter basin mem-v ber 9 havingthe supply basin 10 and the rod support armll. In the rod support arm ll is an opening12 into which the rod 13 is inserted. The rod 13 is held in place by the set screw 14. The rod 13 extends along the bottle and slightly removed therefrom. A band l'extends around the bottle 1 adjacent its outer end,f and also around the rod` 13, being held thereon by the set screw 16. vrThe ro'dl 13 and band l'support the bottle in place over, the basin 1G. The iilter basin' member 9 is recessed at. 17 to hold and support the cover'p'late 1'8 which has the opening 19 through which the bottle neck'projects, While beneath the c'overit is recessed to form the supply basin 10. Centrally of the supply basin and extending outwardly from'the botjtom thereof is the bottle support, comprised'of a plurality of separated prongs or posts 2 0on which .the 'c'ap'2 of the bottle rests. Centrally of this support and in the bottom of the basin l0V is the recess 2l adapted to position and engage the outer end of the plunger. When the bottle is rested on the posts 20, the end of the plunger 5 engages the bottom of the basin 10; this pushes up the closure plate 6 and allows the liquid to flow from s the bottle into lthe basin l0, passing between the posts 20. When ,the bottle is removed from the# support the spring 'l forces the closure plate ,6 down against'the washer'4, which closes the bote tleand prevents spilling the contents when the bottle -is vbeing removed from the basin.

In the bottom of the basin betweenfits sides and the central posts 20 are the raised supports'22 on whichr the filter member 23 rests. rIhis filter memberis shown in FigsIII and IV. This filter member v'comprises the sleeve chamber member '24 having an openingsurrounded by the flange 25. Into thisopening is' fitted the outlet tube or thimble 26, being soldered or otherwise secured therein. Into each end of the sleeve 24 is fitted a sleeve chamber member 27 having the external fiange 28. The ends of a spiral wire supporting member 29 are secured respectively to a flange 28. Over the supporting member 29 is tted the straining member 30 made preferably of some fabric having straining qualities such as felt, canton flannel, or other material. Ihe ends of the member 30 are brought over the flanges 28 and secured down tightly on the body of the sleeve members by the wire rings 31.

The thimble 26 is inserted in the opening 32 of one of the supports 22. Aligned with the thimble and communicating therewith is the feed supply pipe 33 screwed into the opening 32. This pipe communicates with the burner not shown.

The liquid in the basin 10 seeps through the straining member 30 which catches and retards the dirt, sediment, and foreign particles. This strained liquid enters the sleeve portion. of the filter and passes out of the thimble 26 into the supply pipe 33V and goes thence to the burner.

In the basin member 9 and below the bottom of the basin 10 centrally of the posts 20 is the chamber 34; communicating with this chamber Y is the opening 35 leading into the basin 10. Leading from the chamber 34 is the opening 36.' Below the opening 36 is the catch basin member 37 having the-catch basin 33 and the opening 39 communicating with the opening 36. The filter basin member 9 and the catch basin member 37 arev secured together by the threaded nipple 46 in the openings 36 and 39. Thel catch basin is drained by the drain cock 41 in the bottom thereof. Below the catch basin is the boss 42 having the opening 43.

Water, moisture and other liquids heavier than the desired liquid, as well as heavy sediment, and foreign particles, will drop by gravity and iiow through theopeni'ng 35 into the chamber 34 and from there into the catch basin 33 on the bottom of which it will settle. These settlings may be vdrained off by means of the drain cock 41.

Into the opening' 43 of the boss 42 is screw threaded the rod support 44 by which the filter is supported. This rod fits into the stand 45, being adjustably secured therein by the set screw 46. The lter, hence, may be adjusted as to height by means of the rod 44.

The method of operation of the device is as has been described above in connection with the description of the various parts.

The filter 23 may be removed from the basin 10 by simply lifting it out, the nipple 26 being loosely inserted in the opening 32. Sediment andv collected foreign matter may then be easily'removed. In case of wear a new covering 30 may be easily put on the support 29 and secured in place by the rings 31. The parts are easily taken apart for cleaning and replacement. i

From the foregoing description it will be apl parent that I have provided simple, efficient and inexpensive means for obtaining the various advantages of the invention and carrying out the objects thereof, the parts being easily assembled, repaired, replaced, and removed.
